摘　　要：噪声污染为当今世界三大重要污染源之一,其中建筑噪声不仅减少了建筑物及机械结构的寿命,而且降低了居民的工作及居住环境质量,严重危害着居民的身心健康。治理建筑噪声的方法有很多,现大多采用降噪材料对其进行处理,其中降噪材料按降噪机理不同分为吸声材料、隔声材料和阻尼降噪材料。本文针对建筑降噪领域应用,指明了进行建筑降噪的目的及意义,概述了国内外降噪材料的研究现状。此外,介绍了磁流变功能材料的内涵,由于不同类别磁流变材料的特异吸声降噪性能,强调了它在建筑降噪中的重大意义与作用,为保障我国轻噪化可持续发展提供了建议。Noise pollution is one of the three important pollution source in the world today, the construction noise, which not only reduce the life span of buildings and mechanical structure, but also reduce the working and living environment quality of resi- dents, seriously harm the human health. There are many methods to reduce construction noise, the noise reduction materials are mainly used now. According to the different noise reduction mechanism, the noise reduction materials are divided into sound absorption material, sound insulation material and damping material. The goal and the meaning of construction noise reduction is put forward in this article. The state and development tendency of the noise reduction materials are outlined. The connotation of magnetorheological functional material is introduced, and its significant meaning in construction noise reduction is also addressed, which offers suggestions for ensuring the country low-noise＇s sustainable development.
